About Luma Reef

A journal that grows
into an ocean

An interactive diary where every check-in becomes part of a living underwater world, shaped by how you felt when you wrote it.

01 · Write

Every entry
becomes a place

Check in on the Journal page with a few lines about your day, and add photos if you like. Entries stay in your own browser.

02 · Read the mood

AI reads how
it felt

An AI model reads each entry and returns its overall tone, how strongly it's felt, and a few themes. That becomes the color and shape of what grows.

03 · Watch it grow

Your days become
a reef

Coral grows in colors that match each mood. When a day ends, its entries gather into a memory island with a short reflection. The sky above follows your real time and weather.

04 · The Aquarium

Dive in and
talk to a fish

Below the reef is an aquarium made from your entries: a coral for every day, fish on the bright ones, jellyfish on the quiet ones. A small fish companion can see your recent entries and listens. It's not a therapist, and it points you to real support if you need it.

05 · Why I made it

Built with care

LUMA REEF started in a Data & AI course as a question: what does emotional data look like when it becomes something you can see, inhabit, and come back to? It's still a work in progress.
